In a scalene triangle, all sides have different lengths.

A triangle that has no sides that are congruent is a scalene triangle . In a scalene triangle all the side of the triangle have different lengths . An isosceles triangle has two sides that are congruent . An equilateral triangle has 3 equal sides ( All sides are congruent )

This is called a scalene triangle. In math a scalene triangle has no equal sides. This is different from its other two counter parts which are Equilateral and Isosceles triangles. A scalene has no equal sides. An equilateral has 3 equal sides and an Isosceles has 2 equal sides.

All the sides of a scalene triangle are not even. This is the kind of triangle you are describing. Because the sides are not congruent, neither are the angles.

It is a scalene triangle, as all sides have different lengths. It may also be a simlar triangle, as it also have different lengths.
